The Bosch Rexroth LINEAR-SET LSADR2T-20-WV-2000 (R109952088) is a high-precision linear motion set designed for applications requiring rigidity and resistance to torsional loads. This set includes a lightweight precision tandem housing made from aluminum and a precision steel shaft with two ball guide grooves for smooth and accurate movement. The shaft diameter 'd' ensures compatibility with standard lengths as per the provided table, offering flexibility in various installation scenarios. Equipped with two torque-resistant linear bushings, this LINEAR-SET is configured to transmit forces efficiently while maintaining zero clearance thanks to the hardened steel bearing plates that come pre-set from the factory. The design offers stability against cocking loads, making it suitable for applications where precise linear guidance is critical. The LSADR2T-20-WV-2000 is capable of handling dynamic load capacities and static load ratings as indicated by the minimal values provided, considering that loading directions can vary. Its dynamic torsional moment load capacity Mt ensures reliable performance under varying torsional forces. The unit's maximum permissible linear speed vmax and acceleration amax are tailored to meet demanding motion requirements without compromising on efficiency or longevity. This model operates effectively within a wide range of ambient temperatures, from a minimum to a maximum as specified, allowing for use in diverse environmental conditions. It has been designed without external seals but remains relubricatable for ease of maintenance and extended service life. Overall, the Bosch Rexroth LINEAR-SET LSADR2T-20-WV-2000 provides robust performance in linear motion applications where high load capacity, resistance to torsion, and precise guidance are necessary. Its construction assures long-term reliability and consistency in operation, making it an ideal choice for sophisticated mechanical setups requiring high-quality linear motion solutions.

1) Load rating when both Linear Bushings are under equal load. The load ratings indicated are minimal values as the load direction cannot always be clearly defined.
The load ratings are based on a total travel of 100, 00 m. When based on 50 000 m, the  values in the table need to be multiplied by 1.26.

Reduced load capacity with short stroke

In case of short stroke, the service life of the shaft is less than that of the torque-resistant Linear Bushing. The dynamic load ratings C in the tables must therefore be multiplied by the factor fs .

Installation

The Linear Sets come preassembled and set to zero clearance. When pulling out the shaft, the adjusting screws must be loosened and the torque-resistant Linear Bushing reset.

General mounting instructions

Initial lubrication

Torque-resistant Linear Bushings do not come with initial lubrication. Grease Linear Bushings before use, see "Initial lubrication" in the "Lubrication" section.

 

Service life data is based on initial lubrication and relubricated Linear Bushings.

Lubricating a Linear Set with a torque-resistant compact Linear Bushing: on-shaft via Ø = 3.9 lubricating hole until lubricant seeps out. Lubricating a tandem Linear Set: on-shaft via recirculating lubricating groove in middle of outer diameter until lubricant seeps out. Lubricating a flanged Linear Set: on-shaft via funnel-type lube nipple recessed on the end face until lubricant seeps out. technical illustration-R109952088-Linear set (aluminum), DRT2-20-WV-2000, without seal
